IMPROVEMENT IN WINDOW-SHADES.

Specification forming part of Letters Patent No. 201,553, dated March19, 1878 application filed 1 November 19, 1877.

To all whom it may concern:

Be it known that I, THOMAS HENRY PAL- ING, of Woodstock, in the countyof Oxford, in the Province of Ontario, in the Dominion of Canada, haveinvented certain new and useful Improvements on Window-Shades; and I dohereby declare that the following is a full, clear, and exactdescription of the same.

This invention has for its object to retain the cord of a window-shaderoller at any desired position.

It consists of a cord-retaining device constructed of wire spirallycoiled to receive the cord interveningly, and retain it by compressionand jamming therein, and bent rectangularly to form a loop to confinethe cord closely to the cylinder, and having prongs to be driven intothe wood for affixing the device.

Figure l is a front elevation of a windowshade, showing my invention.Fig. 2 is an enlarged view of the cord-retaining device. Fig. 3 is adetail sectional View of the shaderoller transversely, and Fig. 4 is adetail view of the same longitudinally.

A is the curtain or shade; B, abar to which the shade is fastened, andwhich bar is hung to the window-top by hooks and eyes G, or othercontrivance.

D D are cords passing separately through eyes E near the ends of the barB, and con jointly through a central eye, F, the ends attached to atassel, G. The other ends of the cords are attached to spools H H, fixedon the ends of a roller, I, to which the lower end of the shade isattached, so that by pulling down the tassel the cords are unwound fromthe spools, which travel up the window-j ambs on their flanges, takingup the shade on the roller as they go.

When the tassel is lifted or pulled out of contact with thecord-retainer, the weight of the roller carries down the shade as thecords are wound upon the spools.

By my invention I am enabled to dispense with the use of a weightedtassel, and yet retain the cord in all classes of shades using a cordand roller, whereby the roller is held by thecord at any desiredposition.

My cord-retainer consists of a spiral-wire cylinder, J, the ends of thewire turned toward the opposite end of the cylinder rectangularly toform a loop, K, over the same, and

thence downwardly to form prongs, which are driven into the wooden jamborhead of the window-frame. The cord passes through the loop K, by whichit is prevented from swinging out of place when loose, and when theroller is to be retained at any suitable height, the cord is manipulatedto be drawn diametricallybetween the coils of the spiral-wire cylinder,and the compression of the spring in the line of its axis and thejamming of the cord in its angulation retain the cord and prevent itfrom slipping.

The cord is withdrawn by simply pulling it drawings, but is attached tothe windowjamb when a roller is operated at one end by a single cordwinding and unwinding the shade from the roller when journaled near thehead of the window-frame.

The preferred manner of securing the shade to the roller is as follows:L is a longitudinal groove in the roller, and M is a tongue fittingtherein. The end of the shade is inserted in the groove, and confinedtherein by said tongue, and the tongue confined in the groove by spools,on which the cords wind, each spool having a socket or sleeve, N,provided with a slot, which socket fits over the ends of the roller andtongue, the edge of the shade passing into the slot, thus confining thetongue and shade in the longitudinal groove, the slot allowing the sideedges of the shade to nearly touch the flange of the spools.

I claim as my invention- A window-shade cord-retainer consisting of aspiral-wire coil, J, bent to form the loop K,

and the prongs O, by which latter the retainer is directly attached tothe window, substantially as set forth.
